VENTILATOR.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed March 27, 1905. Serial No. 252,157.

T0 to whom it may concern:

Be it known that I, J AOOB LORENZ, a citizen the advantage ofautomatically protecting the interior of a house from rain or dustcaused by sudden winds when it is located in such a position as to beexposed to the weather.

In the accompanying drawings, in which like numbers of reference denotelike parts wherever they occur, and forming a part of thisspecification, Figure 1 is a perspective view of a house-shutterequipped with my device. Fig. 2 is a fragmentary view, partly insection, with one of the side panels removed, exhibiting the V-shapedslats in the ventilating position. Fig. 3 is a View similar to the last,showing the V-shaped slats in a different position. Fig. 4 is'afragmentary view, partly in section, showing the manner of attachment ofthe V-shaped slats to the side panels of the shutter. Fig. 5 is afragmentary top plan View, partly in section, of one of the slats,showing its attachment to the side panel and also to thecontrolling-rod. Fig. 6 is a perspective fragmentary detail of thefacing to the side frames, which directly receives the ends of theslats; and Fig. 7 is a perspective view showing one end of one of theslats.

This construction may be applied in the partitions of rooming-houses,state-rooms on ships and boats, transoms over doors, doors themselves inthe form of a removable panel set in a window-frame upon which thewindow-sash is closed down, and in a variety of other ways. In thedrawings, however, I have illustrated it as applied to an ordinarywindow-shutter, as the description of the construction'and operation ofthe several parts in connection with a shutter will sufficiently showhow the same can be adapted to or applied in any of the several useshereinabove suggested or any others that may be appropriate.

The shutter-frame or equivalent structure is shown formed of the sidepanels 1 and top and bottom cross-pieces 2. The space within this frameis provided with a plurality of V- shaped slats 3, each of which isprovided on the inside with perforated extensions 4:, through theperforations 5 in which the staples 6 loop to attach the controlling-rod7 to all the slats 3, so that they may move or be moved in unison.

Each of the V-shaped slats 3 is pivoted at the union of its arms in thefacing-cleats 8, as clearly shown in Figs. 2, 3, 4:, and 5. The means ofpivoting may be varied; but Ihave exhibited the same in the drawings asaccomplished by means of rods 9 in fixed connection (as by soldering)with the V-shaped slats 3, said rods being located at the bend of the Vand extending into the openings or recesses 10 in the cleats 8, therebeing one such cleat at each side of the frame. The material of whichthe cleats 8 are made is slightly enlarged or bulges around each of theopenings or recesses 10 for the sake of strength.

Each of the V-shaped slats 3 is notched at both ends, as at 11, andreceives in said notches the cieats 8, which, as clearly depicted inFigs. 4 and 5, fit closely up to the bend of the V in the slats 3 andfill in all the space between same and the side panels 1, therebyleaving no peepholes or cracks at the ends of the slats. The ends of therods 9, as will be observed in Figs. 5 and 7, project out into saidnotches 11, but registering with the recesses or openings 10 arereceived thereinto.

The cleats 8 are removable from the posi tion illustrated in thedrawings, being loosely mounted on the tongue 12, which projects upwardfrom the bottom cross-piece 2 and seats in the recess 10 in the cleats8, said tongue 12 extending the full length of the bottom cross-piece 2,so as to preclude vision. The upper end of the cleats 8 may be fixed inany desired manner.

Normally the slats 3 will occupy the position shown in Fig. 2, whichallows free circulation of the air, but absolutely precludes observationfrom without of the inside of the room or house so equipped. In case ofa sudden Windstorm with accompanying dust, if the wind blows from leftto right in Fig. 3 the slats will at once assume the position of thatfigure, the dust being thus obviously excluded. In like manner and forthe same reason rain could not enter, and in case of rain unaccompaniedby wind the slats in the position of Fig. 2 would be a perfect watershedand keep the rain out. If the wind blew in a draft through the house andin a direction of from right to left, in Fig. 3, the reverse movement tothat above described would result, obviously equally excluding dust andrain.

Having thus described my said invention, what Iclaim, and desire tosecure by Letters Patent, is

1. In a device of the character described, the combination of aplurality of notched V- shaped slats, means for pivoting same projectinginto said notches, and means projecting into said notches for receivingsaid pivotal projections.

2. In a device of the character described, the combination of aplurality of V-shaped slats, said slats'having notches at both ends androds fixed to said slats extending into the notches at both ends, and aframe, pivotal connection with said frame being made by means of theprojecting ends of said rods.

3. In a device of the character described, the combination of aplurality of V-shaped slats, said slats having notches at both ends androds fixed to said slats extending into the notches at both ends, aframe, pivotal connection with said frame being made by means of theprojecting ends of said rods, and means adjoining said frame andreceived in said notches to prevent vision through said notches.

4:. The combination with a frame of an upwardly-extending tongue seatingon the lower rail thereof, removable cleats seating on-said tongue, andsecured to the side rails of the frame, and V-shaped slats notched attheir ends to receive said cleats and being supported thereby. V

5. The combination with a frame of cleats secured thereto, and V-shapedslats pivotally supported by said cleats and being notched at their endsadjacent the apex to receive said cleats.

6. The combination with the frame having cleats, of V-shaped slatspivotally supported by the cleats and being notched at their ends toreceive said cleats, and having their movement restricted by engagementof the legs of the slats with said cleats.

7. In combination with a frame, V-shaped slats notched at their endsadjacent the apex thereof, and means for affording a pivotal connectionbetween the slats and frame extending into each of said notches.

8. In combination with a frame, V-shaped slats notched at their endsadjacent the apex thereof, and means carried by said slats and extendinginto said notches for pivoting the slats to the frame.

9. In combination with a frame, rods having their ends supportedthereby,and V-shaped JACOB LORENZ. Witnesses:
